Conor McGregor Makes Highly Anticipated Return at UFC 329
Conor McGregor will step into the Octagon for the first time in over five years when he faces Max Holloway in the main event of UFC 329 on Saturday 11 July 2026 at the T-Mobile Arena in Las Vegas. The former two-division champion has not fought since breaking his left leg in his trilogy bout with Dustin Poirier in July 2021. His comeback has been one of the most talked about events in mixed martial arts history, and the numbers reflect that. McGregor is reported to have broken a UFC record with a guaranteed purse of $21 million for this fight, surpassing his previous high of $15 million for the Poirier fight. The announcement was made on Thursday 9 July and has dominated headlines across the sport.
The buildup to UFC 329 has been characteristically fiery. At the final press conference on 9 July, McGregor and Holloway had to be separated by security after a tense face off. Holloway, who lost to McGregor via decision in August 2013, is looking for revenge in what will be his welterweight debut. Speaking to the media, Holloway said he hopes McGregor is competitive and makes him think he can do it one more time, rather than winning easily. McGregor, meanwhile, has been predictably brash, predicting a knockout and boasting about knocking out multiple training partners during his camp.
Background: A Rematch 13 Years in the Making
When Conor McGregor and Max Holloway first met at UFC Fight Night 26 in August 2013, both were unranked featherweights looking to make a name. McGregor won that fight by unanimous decision, but Holloway has since become a legend in his own right. He captured the UFC featherweight championship in 2017 and defended it three times before losing to Alexander Volkanovski. Holloway then moved up to lightweight and challenged for the BMF title, losing to Charles Oliveira in October 2025. That defeat snapped a two fight winning streak and left Holloway at a career crossroads. Now at 34, he moves up to 170 pounds for the first time, betting on his durability and volume striking to overwhelm a rusty McGregor.
McGregor, now 38, has not won a fight since January 2020 when he knocked out Donald Cerrone in 40 seconds. Since then he has lost twice to Poirier and suffered a horrific leg injury. His time away has been filled with legal issues, including a civil rape case that he addressed for the first time this week, calling himself an innocent man. He has also been embroiled in a war of words with Justin Gaethje, calling the BMF champion a bum and referencing Holloway's knockout of Gaethje in April 2024. Despite the layoff, McGregor remains the biggest draw in the sport, and UFC CEO Dana White has already mapped out five scenarios for McGregor after UFC 329, according to reports.
Weight and Career Implications
Both men are making significant weight changes for this bout. Holloway steps up to welterweight for the first time, while McGregor returns to 170 pounds where he has fought twice before (against Nate Diaz and Donald Cerrone). Robert Whittaker, who moves up to light heavyweight on the same card, told media that the change is life changing and he trained at the same weight as always, which suggests the lighter divisions are becoming increasingly difficult for older fighters. McGregor's future at lightweight appears over; he stated this week he won't be back at 155 pounds. A win on Saturday could set up a title shot at welterweight against champion Islam Makhachev, while a loss might spell the end of McGregor's career.
The UFC 329 Card: Depth and Storylines
UFC 329 is stacked from top to bottom. The co main event features Paddy Pimblett against Benoit Saint Denis in a lightweight bout with title implications. Saint Denis is a slight favourite and expects a Fight of the Night performance, citing Pimblett's toughness. Pimblett has been vocal this week, telling Arman Tsarukyan to stop eating and fight. The winner could be one fight away from a shot at Makhachev.
Another pivotal bout sees Robert Whittaker move up to light heavyweight to face Nikita Krylov. Whittaker, a former middleweight champion, is on a two fight losing streak and hopes the weight cut relief will extend his career. He told media it is honestly life changing. His teammate in PFL confirmed Whittaker trained at the same weight as always, indicating he had not cut much for middleweight.
Other notable fights include Cory Sandhagen rematching Mario Bautista in a bantamweight bout. Sandhagen explained why he will be difficult for Bautista to deal with. Adrian Yanez faces former champion Cody Garbrandt, with Yanez expecting a war between two heavy handed guys. The card also features Tracy Cortez making her return after calling out entitled fans. Alexa Grasso returns at Noche UFC, not on this card, but was announced separately for a later event. Israel Adesanya's shocking split from City Kickboxing dominated headlines on 9 July and will be covered in the next section.
Israel Adesanya Splits from City Kickboxing After Four Straight Losses
In breaking news on 9 July, former middleweight champion Israel Adesanya announced he is leaving City Kickboxing and head coach Eugene Bareman. Adesanya has lost four consecutive fights, including three title fights (twice to Dricus du Plessis and once to Sean Strickland) and a decision loss to Khamzat Chimaev at UFC 330. The split is a seismic shift in MMA, as Adesanya and City Kickboxing have been synonymous since his UFC debut in 2018. The New Zealand born Nigerian has been with the gym for over a decade, rising from kickboxing prospect to one of the greatest middleweights ever. However, recent struggles and a desire for a fresh start appear to have driven the decision.
The news comes just two days before UFC 329, but Adesanya is not on the card. He is expected to take time to decide his next move, which could include a move to a new gym or a period of reflection. His last fight was a unanimous decision loss to Chimaev at UFC 330 on 28 June 2026. Adesanya has not won since September 2023 when he defeated Sean Strickland. The departure raises questions about his future at 185 pounds and whether a change of scenery can revive his career. City Kickboxing also houses fighters like Dan Hooker and Carlos Ulberg, but Adesanya was the flagship athlete.
Fighter Pay, Personal Feuds and Other Headlines
McGregor has used the lead up to UFC 329 to speak out on fighter pay, an ongoing issue in the UFC. He criticised the promotion's revenue share model and called for better compensation for lower tier fighters. This is a rare moment of solidarity from the sport's highest earner. Holloway also addressed pay, claiming he will make the highest payday of his career for this fight despite the end of pay per view points under the new ESPN broadcast deal. He urged other fighters to get new management if they are not earning big money.
Another story involves Dustin Poirier's recent public intoxication arrest in Louisiana. McGregor criticised Poirier for blaming his father for the incident, telling him to take accountability. McGregor posted on social media calling Poirier a bum, a term he has also used for Justin Gaethje. Gaethje meanwhile picked Ilia Topuria to beat Paddy Pimblett in a potential future fight, calling Topuria dangerous and Pimblett goofy. The lightweight division is bubbling with tension.
Elsewhere, Terrance McKinney warned King Green about trash talking ahead of their UFC 329 clash. BKFC champion praised McGregor's need for a return, saying fighting is all we know. Nico Carrillo steps into kickboxing at ONE Fight Night 46. Jonathan Haggerty locks in a ONE world title defence against Hiroki Akimoto at ONE SAMURAI 4. And Chael Sonnen praised heavyweight prospect Josh Hokit's character development despite a recent interview controversy.
What's Next for Conor McGregor and the UFC After UFC 329
The outcome of the main event will shape the welterweight division and the entire UFC landscape for the rest of 2026. If McGregor wins, Dana White has five scenarios ready, likely including a title shot against Islam Makhachev at UFC 330 or a blockbuster bout with YouTuber turned boxer Jake Paul. If Holloway wins, he becomes a factor at 170 pounds and could face the winner of Makhachev vs a future contender. McGregor has also hinted at a possible boxing rematch with Floyd Mayweather, though that seems unlikely given Mayweather's age and the failed 2017 superfight.
Beyond McGregor, the Adesanya situation will be a major storyline. If he decides to change gyms, he could join American Top Team, Xtreme Couture, or a new team in New Zealand. The middleweight division is currently ruled by du Plessis, and Adesanya may need to win two or three fights to earn another title shot. Robert Whittaker's light heavyweight move could also reignite his career; a win over Krylov might put him in contention for a title shot at 205 pounds, currently held by Alex Pereira.
The fan interest in UFC 329 is unprecedented. According to reports, the event is expected to break the all time gate record held by UFC 205 at Madison Square Garden. McGregor's return has also boosted betting action, with McGregor as a slight underdog despite his star power. The fight is a fascinating clash of styles: McGregor's left hand power and counter striking against Holloway's relentless pressure and volume. After five years, the MMA world is ready to see if Conor McGregor can still defy the odds.
Closing: A Defining Moment for Two Legends
UFC 329 represents more than just another pay per view. It is a referendum on Conor McGregor's legacy, a chance for Max Holloway to avenge an old loss, and a showcase of a deep roster of talent. The card features rematches, weight class changes, and emotional storylines. Whether McGregor returns to his glory or Holloway writes a new chapter, the event will be remembered as one of the most significant in UFC history. The world will be watching on Saturday night.
